"description": "\n Rank merchants that can actually fulfill a purchase need, by honest signals only.\n\n Args:\n category: product category, e.g. \"vodka\".\n ship_to: ISO region the order must ship to, e.g. \"US-FL\".\n require_age_gate: only return merchants that enforce 21+.\n limit: max results.\n optimize_for: what matters to the BUYER -- \"trust\" (default), \"price\"\n (lowest matched price), or \"speed\" (same-day, then next-day\n fulfillment). Ties always break by earned trust.\n product_type/dest_state/channel: pass all three (e.g. \"spirits\", \"FL\",\n \"ship\"|\"local_delivery\") for STRICT COMPLIANCE mode -- only merchants\n with attested age-gate + attested license + a legal jurisdiction\n path are returned, each with its compliance verdict.\n Every result carries ships_to states (match them against where the buyer\n lives), best_price, and the evidence behind the record. Paid placement never\n affects any ranking (ranking_basis states the basis actually used).\n ",
